title: Preparation of drugs used in hyperacidity. Part IV. Effect of sulphate, chloride and nitrate ions and mannitol on neutralizing properties and changes of alumina gels.
abstract: The stability of alumina gels precipitated from the appropriate aluminum salts with ammonia solution have been investigated. The effect of SO42-, Cl-, NO3-ions and mannitol on this stability was evaluated. SO42-ions, and to a lesser degree also Cl- and NO3-ions stabilize alumina gel due to the incorporation in its structure. The use of mannitol solution as a suspension medium results also in the complete stabilization of the gel.
